Question

previously i have added a ontouch listener to textviews which will do a custom vibration upon each touch.

however when i hold the textview it will keep playing out the custom vibration.

how do i set it so that it would only vibrate only once per touch even when i am holding on the textview

i tried onclick and a few other listeners but it doesn’t do what i want.. as i require the textview to do the vibration on touch as they go from 1 textview to another

public boolean onTouch(View v, MotionEvent event)
{
    vibratePattern();
    return true;
}
private void vibratePattern()
{
    Vibrator vibrator;
    vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
    int dot = 100;
    int dash = 250;
    int short_gap = 200;
    int medium_gap = 500;
    int long_gap = 1000;
    long[] pattern101 = {
        0,
        dot, short_gap, dash, short_gap, dot,
        long_gap
    };

    vibrator.vibrate(pattern101, -1);
}

Answer 1

It might be something in your vibratePattern method, but this should work and vibrate only once if you check for correct action on the event:

if (event.getAction() == ACTION_DOWN) {
    Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
    vibrator.vibrate(100);
}

UPDATE:

If that won’t work with multiple views, then you could attach the same listener to all views and check when the v reference changes:

if (previousView != v) {
    vibratePattern();
    previousView = v;
}
return true;
